SECTION 2.5 Thermal Effects 163 Problem 2.5-15 Pipe 2 has been inserted snugly into Pipe 1, but the holes for a connecting pin do not line up: there is a gap s . The user decides to apply either force P 1 to Pipe 1 or force P 2 to Pipe 2, whichever is smaller. Determine the following using the numerical properties in the box. (a) If only P 1 is applied, find P 1 (kips) required to close gap s ; if a pin is then inserted and P 1 removed, what are reaction forces R A and R B for this load case? (b) If only P 2 is applied, find P 2 (kips) required to close gap s ; if a pin is inserted and P 2 removed, what are reaction forces R A and R B for this load case? (c) What is the maximum shear stress in the pipes, for the loads in (a) and (b)? (d) If a temperature increase ± T is to be applied to the entire structure to close gap s ( instead of applying forces P 1 and P 2 ), find the ± T required to close the gap. If a pin is inserted after the gap has closed, what are reaction forces R A and R B for this case?
